Development of High Pressure Ball Valve Pressure Maintaining Performance Test System

This study proposes a testing method for the voltage stabilization performance of high-pressure multifunctional ball valves and develops an automated testing platform based on LabVIEW. The testing system adopts a voltage stabilization strategy controlled by a frequency conversion motor and an electromagnetic overflow valve, and real-time acquisition and analysis of pressure data are achieved through LabVIEW software. During the experiment, the system is able to accurately control the test pressure and automatically record the pressure time variation curve, ultimately generating stable pressure characteristic curves for different pressure ranges. This testing method provides a reliable technical means for the performance evaluation of high-pressure ball valves. The testing platform has the characteristics of high automation, accurate data acquisition, and easy operation.
